Variables ¶
var ( ErrCritical = ClassGlobal.New(CodeExecResultIsEmpty, "critical error %v") ErrResultUndetermined = ClassGlobal.New(CodeResultUndetermined, "execution result undetermined") )
Global error instances.
var ( // ErrClassToMySQLCodes is the map of ErrClass to code-map. ErrClassToMySQLCodes map[ErrClass](map[ErrCode]uint16) )
Functions ¶
func ErrorEqual ¶
ErrorEqual returns a boolean indicating whether err1 is equal to err2.
func ErrorNotEqual ¶
ErrorNotEqual returns a boolean indicating whether err1 isn't equal to err2.
Types ¶
type ErrClass ¶
type ErrClass int
ErrClass represents a class of errors.
const ( ClassAutoid ErrClass = iota + 1 ClassDDL ClassDomain ClassEvaluator ClassExecutor ClassExpression ClassInspectkv ClassKV ClassMeta ClassOptimizer ClassOptimizerPlan ClassParser ClassPerfSchema ClassPrivilege ClassSchema ClassServer ClassStructure ClassVariable ClassXEval ClassTable ClassTypes ClassGlobal ClassMockTikv ClassJSON )
Error classes.
func (ErrClass) EqualClass ¶
EqualClass returns true if err is *Error with the same class.
func (ErrClass) New ¶
New creates an *Error with an error code and an error message. Usually used to create base *Error.
func (ErrClass) NotEqualClass ¶
NotEqualClass returns true if err is not *Error with the same class.
type ErrCode ¶
type ErrCode int
ErrCode represents a specific error type in a error class. Same error code can be used in different error classes.
const ( // CodeUnknown is for errors of unknown reason. CodeUnknown ErrCode = -1 // CodeExecResultIsEmpty indicates execution result is empty. CodeExecResultIsEmpty = 3 // CodeMissConnectionID indicates connection id is missing. CodeMissConnectionID ErrCode = 1 // CodeResultUndetermined indicates the sql execution result is undetermined. CodeResultUndetermined ErrCode = 2 )
type Error ¶
type Error struct {
// contains filtered or unexported fields
}
Error implements error interface and adds integer Class and Code, so errors with different message can be compared.
func (*Error) FastGen ¶
FastGen generates a new *Error with the same class and code, and a new formatted message. This will not call runtime.Caller to get file and line.
func (*Error) Gen ¶
Gen generates a new *Error with the same class and code, and a new formatted message.
func (*Error) GenByArgs ¶
GenByArgs generates a new *Error with the same class and code, and new arguments.
func (*Error) Location ¶
Location returns the location where the error is created, implements juju/errors locationer interface.
func (*Error) MarshalJSON ¶
MarshalJSON implements json.Marshaler interface.
func (*Error) ToSQLError ¶
ToSQLError convert Error to mysql.SQLError.
func (*Error) UnmarshalJSON ¶
UnmarshalJSON implements json.Unmarshaler interface.
